Thats a great set up. I dont think anyone will tell you to change anything. Witht he RAM and the motherboard you should get a real nice OC. The only thing that would limit it is the HSF but even then youll be able to do real well.

is there a better HSF i should get? the ninja? I've heard good stuff about both the ninja and the BT so I just chose the BT.

The Xp-90 is also a good offering. What I meant by that though was that its the next best thing to water, not low quality.
